TF2 crashing during a specific Death Run map

TF2 crashing during a specific Death Run map
This is a problem that I can't seem to find fixes for anywhere. Even though my game works perfectly on any other map, if I join the map dr_safety_first_skial, the game crashes after a few minutes with the message:

As usual, lowering the texture quality does not help. Is there any way to fix this problem? I love that map, so me not being able to play it before crashing after a few minutes is kind of disappointing.
